Step 1: Install Node.js and npm

Before setting up Next.js, ensure you have Node.js installed. You can download it from nodejs.org.

Check if Node.js and npm (Node Package Manager) are installed by running:

node -v  # Check Node.js version
npm -v   # Check npm version

---

Step 2: Create a New Next.js Project

Run the following command to create a Next.js project:

npx create-next-app@latest my-next-app

Replace my-next-app with your desired project name. The above command will set up a Next.js project with all the necessary configurations.

Alternatively, you can use:

yarn create next-app my-next-app

If you’re using Yarn instead of npm.

---

Step 3: Navigate to Your Project Directory

Once the installation is complete, move into the project folder:

cd my-next-app

---

Step 4: Run the Development Server

Start the Next.js development server with:

npm run dev

or

yarn dev

By default, your app will run on http://localhost:3000. Open it in your browser to see your Next.js app in action.

Step 5: Understanding the Next.js Folder Structure

A Next.js project includes the following key directories and files:

• pages/: Contains the application’s pages. Each file represents a route.
• public/: Stores static assets like images and fonts.
• styles/: Contains global and component-specific CSS files.
• next.config.js: The configuration file for customizing Next.js behavior.

Step 6: Creating Pages in Next.js

Next.js uses a file-based routing system. To create a new page, simply add a file inside the pages/ directory.

For example, create a new file about.js inside pages/ and add:

function About() {
  return <h1>About Us</h1>;
}

export default About;

Now, visit http://localhost:3000/about to see your new page!

---

Step 7: Styling Your Next.js App

You can style your pages using CSS modules or global styles.

Example of using CSS modules:

1. Create a new file Home.module.css inside styles/.
2. Add the following CSS:

.title {
  color: blue;
  font-size: 2rem;
}

3. Import and use it in pages/index.js:

import styles from '../styles/Home.module.css';

export default function Home() {
  return <h1 className={styles.title}>Welcome to Next.js!</h1>;
}

---

Step 8: Deploying Your Next.js App

Once your Next.js app is ready, deploy it using Vercel, the creators of Next.js.

1. Install Vercel CLI:npm install -g vercel
2. Run:vercel
3. Follow the on-screen instructions to deploy your app.

Alternatively, you can host your Next.js app on platforms like Netlify, AWS, or DigitalOcean.
